Onboard navigation - The near-earth optionsThis paper summarizes anticipated onboard navigation accuracies and user system characteristics for near-earth spacecraft. Alternate onboard systems configurations using inputs from the Tracking and Data Relay Satellite System (TDRSS) and the DOD NAVSTAR Global Positioning System (GPS) are described. Initial simulation results indicate that TDRSS will provide accuracies of 100 meters or less, and GPS can permit user spacecraft orbit determination to within 10 meters. Specific GPS user equipment developments for Landsat-D and Shuttle are outlined, along with future low-cost versions of these systems.
